Ren, Yibin and Wang, Hao and Huang, Jingjing and Zhang, Bingchun and Yang, Ke (2007) Study of biodegradation of pure magnesium. In: ASBM7: 7th Asian Symposium on Biomedical Materials , 20-23 Aug 2006, Jeju, Korea.
Magnesium and its alloys are possible to develop new type of biodegradable medical magnesium alloys by using their active corrosion potential. The bio-corrosion properties of the high pure magnesium in the Hank's solution were investigated in this paper, the results showed that high pure magnesium had a low corrosion rate and hydrogen release in Hank's solution, when the pH value of solution was controlled at 7.5, the corrosion rate was under 0.2mm/year, the production of hydrogen was about 0.15ml/cm2, and if the solution wasn't controlled on pH value, the corrosion rate was about 0.02 mm/year, production of hydrogen was about 0.1 ml/cm2. Result of in vitro Kinetic clotting time test and animal implant prep-test showed that High pure magnesium had good thromboresistant property and tissue compatibility, pure magnesium can biodegrade lowly in animal body and formed surface apatite, which proportion of Ca/P was similar with bone tissue.
